Abstract (en)
[origin: US7112389B1] Alkaline and lithium batteries are disclosed that advantageously include separators comprising at least one porous layer of fine fibers having a diameter of between about 50 nm and about 3000 nm that provide improved combinations of reduced thickness, dendritic barrier against short-circuiting and low ionic resistance as compared with known battery separators.
